Basic Network VLAN and Subnet Architecture Advice, Please
Posted on 2014-10-29
We are looking at redesigning our network core with some new VLANs and subnets. (something much easier to manage than what we have now). I'm looking for some guidance, or at least a 'thumb's up' on what we're doing. Thanks!
VLAN 100 - 172.16.100.0/22
Desktops, laptops, smartphones, end user devices, etc.
VLAN 110 - 172.16.110.0/23
VLAN 120 - 172.16.120.0/24
VLAN 130 - 172.16.130.0/24
VM Servers, ESXi hosts, SANs
VLAN 140 - 172.16.140.0/24
Network devices, switches, routers, etc.
VLAN 150 - 172.16.150.0/24
Note: This is a fiber channel network, so the hosts and SANs will have a couple FC and several gigabit NICs.
Is this a decent plan?
Do you think there is an issue with putting ESXi hosts and SANs in the same VLAN/subnet as VM servers?
Should printers and end user devices be split up?
Any other thoughts or advice are welcomed.
